RNA editing in Trypanosoma brucei is a posttranscriptional processing event that results in the addition and deletion of uridine residues within several mitochondrial mRNAs. We have examined reactions involving pre-edited precursor RNAs in vitro. In this study, we report specific cleavage of pre-edited cytochrome b (CYb), cytochrome oxidase subunit II (COII), and cytochrome oxidase subunit III ...

In this work, we report the electrochemical response of a family Co(II) complexes, [CoII(L)3]2+ and [CoII(L’)2]2+ (L = 2,2’-bipyridine, 1,10-phenanthroline, 3,4,7,8-tetramethyl-1,10-phenanthroline, 5,6-dimethyl-1,10-phenanthroline, 4,7-diphenyl-1,10-phenanthroline; L’ terpyridine 4-chloro-terpyridine), in presence absence CO2 order to understand role redox potential molecular structure on catal...

VT transition from the high-spin CoII to low-spin CoIII state was observed for complex (N-cyclo-hexyl-2-iminopyridine)(3,6-di-tert-butyl-o-benzosemiquinonato)(3,6-di-tert-butyl-catecholato)cobalt in both solid and liquid form. For first time we demonstrate a low-temperature nanosecond pump-probe XANES experiment revealing valence tautomeric solution of Co complex. Reversible induced under tempe...

The Cover Feature shows light-driven hydrogen evolution mediated by cobalt(II) tripodal iminopyridine complexes, using tri(n-butyl)triazatriagulenium (TATA+) as the organic sensitizer and triethylamine (TEA) sacrificial donor in aqueous acetonitrile. activity of complexes depends highly on electronic properties substituents pyridine moieties. Under acidified conditions, for H2 production was en...

We have studied partially edited molecules for the cytochrome-c oxidase subunit III (COIII) transcript from two species of the insect trypanosome Herpetomonas. We found unexpected patterns of editing, in which editing does not proceed strictly 3' to 5', in 24 of 61 partially edited clones. A comparison of the partially edited molecules between the two kinetoplastid species revealed an 8- to 10-...

Background With some exceptions, mitochondria within the class Insecta have the same gene content, and generally, a similar gene order allowing the proposal of an ancestral gene order. The principal exceptions are several orders within the Hemipteroid assemblage including the order Thysanoptera, a sister group of the order Hemiptera. Within the Hemiptera, there are available a number of complet...

In this work, a new cobalt(III) complex, [Co(HEAC)2]ClO4’”2.5H2O (1), with the HEAC, 2(2-(2-hydroxyethylamino)ethylamino)cyclohexanol, was prepared and identified by elemental analysis, FT-IR and UV-Vis spectroscopy, cyclic voltammetry and single-crystal X-Ray diffraction. The cobalt atom in the crystal structure of 1 has a distorted octahedral geometry by coordination of the four nitrogen and ...
